Add markers of entrance/exit sphere of influence for relative trajectory view

[Vortygont]

Hard to differ points of entrance and exit for sphere of influence by only moving circles animation. For example how it looks like when after creating transfer manevour to Minmus I focused on it

Visually it is hard to determine entrance and exit if you don't know in advance how their animations look like. And also I believe that it is very hard to remember for which case circles converge and diverge, especially for new players. Cost of mistake is high - you will get retrograde orbit instead of prograde, and reverse. I believe there must be markers for them in all cases, in this case for relative to Minmus view

Upd: I describe problem for 0.1.1.0 version of ksp2
